69°F is not just cold, it’s FREEZING cold. Yesterday we were in a mall and in one of the rooms the air-condition was set on 69°F. It was really cold. We were all freezing, having goose-bumps. After a while I asked the staff if they could turn it up a little. He did so and turned it on 78°F. That was a lot better. Although we weren’t freezing anymore, the first freezing temperature had it’s effects: I now have a sore throat and a stuffy nose. Great.
